Have you experienced pain or tingling in your hands or feet? Those are signs of possible neuropathy, “a general term for nerve dysfunction in your limbs,” says Eva Feldman, a professor of neurology at the University of Michigan Medical School in Ann Arbor.
The likelihood of neuropathy appears to increase with age. That’s partly because the number of nerve cells in your body declines over the years, and those that remain become less functional. And “if they are damaged by injury or an underlying medical condition, they struggle more to recover,” says Anne Louise Oaklander, an associate professor of neurology at Harvard Medical School.
Chronic conditions such as diabetes, as well as autoimmune disease and treatments such as some kinds of chemotherapy, can cause neuropathy, too, Oaklander says. Long-term untreated hypothyroidism, kidney disease and obesity also can increase the risk, according to the Mayo Clinic. Another potential cause is vitamin B12 deficiency, which is thought to affect at least 20 percent of adults over age 60, says Kunal Desai, an assistant professor of neurology at the Yale School of Medicine in New Haven, Connecticut. Here’s what to do if you think you have neuropathy.
Tingling or painful sensations in your hands and/or feet are the main symptoms. “Patients often describe it as feeling like ants crawling on their feet, or even as prickling or burning,” Feldman says. Another red flag is numbness in your hands or feet that leaves you feeling unsteady.
If you have any of the above, call your doctor right away. That’s especially important if you have a chronic condition such as Type 2 diabetes or you’re being treated with certain chemotherapy drugs.
Getting diagnosed
Your primary care practitioner will examine you, including the skin on your hands and feet, to look for fissures or cracks. They’ll test your reflexes and might use a tuning fork in the area to see whether you can feel the vibration or prick you with a pin to see whether you feel pain. They might check the strength in your hands and feet, as well.
If any results are abnormal, you’ll probably have tests of your nerves for confirmation and, if those results are abnormal, blood tests to check for contributing conditions such as Type 2 diabetes, Oaklander says. If the neuropathy is on only one side or is worse on one side, Feldman says, you’ll need to see a neurologist to rule out more serious conditions such as amyotrophic lateral sclerosis.
Finding relief
How your neuropathy is treated usually depends on the cause, Feldman says. If it’s Type 2 diabetes, exercise and weight loss, if needed, can improve symptoms, according to a 2022 review in the journal Lancet Neurology. Neuropathy due to an autoimmune disorder, hypothyroidism or a vitamin B12 deficiency often eases once the underlying condition is corrected. If it’s caused by chemotherapy, your doctor may change your regimen or advise a treatment break.
